I wouldn't doubt that there are some ways to make it better.. that was a
quick throw-together that took me about 5 minutes to make.
The reason it's "$PHP_MYSQL" != "yes" is because it's called from after
it's been determined that the user wants MySQL support, and a value of
"yes" is the value that is passed if the user wants to use the built-in
library (or so I could tell by reading the code..). I suppose most of that
could be rewritten to, perhaps something like the following:
AC_DEFUN(PHP_MYSQL_VERSION,[
if test "$PHP_MYSQL" != "yes"; then
AC_MSG_CHECKING(for MySQL version)
if test -x "$PHP_MYSQL/bin/mysql_config"; then
AC_MSG_RESULT(3.23 or better)
PHP_EVAL_LIBLINE($PHP_MYSQL/bin/mysql_config --libs)
else
AC_MSG_RESULT(3.22 or earlier)
fi
fi
])
(yet another 5 minute job.. I don't see any bash-isms in there, but there
could be some..)
Of course, this should only be called once it's been determined that the
user wants MySQL support and they don't want the built-in library..

PS: This is just an example.. as I mentioned, I'm sure there are better
ways to write it.
